The Welding Wire Deposition Efficiency Calculator finds percent deposition efficiency of a welding wire or welding electrode without stub loss.
INSTRUCTIONS: Choose units and enter the following:
Deposition Efficiency (`D`): The calculator returns the answer as a percent.
For estimates of how stub loss affects deposition efficiency, view the table below:
| Electrode Length | Deposition Efficiency | 2" (50mm) STUB | 3" (75mm) STUB | 4" (100mm) STUB | 5" (125mm) STUB |
|---|---|---|---|---|---|
| 12" (300mm) Electrode | 60% | 50% | 45% | 40% | 35% |
| 65% | 54.2% | 46.7% | 43.3% | 37.9% | |
| 70% | 58.3% | 52.5% | 46.6% | 40.8% | |
| 75% | 62.5% | 56.2% | 50% | 43.7% | |
| 80% | 66.6% | 60% | 53.3% | 46.6% | |
| 14" (350mm) Electrode | 60% | 51.4% | 47.1% | 42.9% | 38.8% |
| 65% | 55.7% | 51.1% | 46.4% | 41% | |
| 70% | 60% | 55% | 50% | 45% | |
| 75% | 64.3% | 56.9% | 53.6% | 46.2% | |
| 80% | 68.5% | 62.8% | 57.1% | 51.4% | |
| 18" (450mm) Electrode | 60% | 53.3% | 50% | 46.6% | 43.3% |
| 65% | 57.7% | 54.2% | 50.5% | 46.9% | |
| 0% | 62.2% | 56.3% | 54.4% | 50.5% | |
| 75% | 66.6% | 62.5% | 56.3% | 54.2% | |
| 80% | 71.1% | 66.6% | 62.2% | 57.7% |
To find the deposition efficiency, use the formula:
D = M / E
